FLOOD-GATE FOR FENCES CROSSING STREAMS.

SPECIFICATION forming part of Letters Patent No. 751,023, dated February2, 1904.

Application filed October 6, 1903.

To all whom, it may concern.-

Be it known that 1, CHARLES SPIVEY, aoiti- Zen of the United States,residing at Sutton, in the county of Clay and State of Nebraska, haveinvented certain new and useful Improvements in Flood -Gates for FencesCrossing Streams, of which the following is a specification.

This invention provides an automaticallyoperable gate to be used forspanning small streams or watercourses and adapted to normally remainclosed except when the stream is at flood height, when by operation ofcertain means provided for the purpose the gate will open suflicient topermit passage of debris or the like carried by the water.

The gate is preferably utilized to form a continuation of a fence whichextends in the direction upon opposite sides of the gate, though, aswill be obvious, the invention in other adaptations is very serviceable.

For a full desciption of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand drawings hereto attached.

While the essential and characteristic features of the invention aresusceptible of modification, still the preferred embodiment of theinvention is illustrated in the accompanying drawings, in which Figure 1is a perspective view of a gate embod ying the invention, showing thesame closed. Fig. 2 is a sectional view on the line X X of Fig. 1,portions of the gate structure being broken away. Fig. 3 is a sideelevation showing the cooperating device for looking the gate in closedposition, the gate when opened being disposed approximately in theposition indicated by the dotted lines.

Corresponding and like parts are referred to in the followingdescription and indicated in all the views of the drawings by the samereference characters.

As shown in the drawings, the gate is mount ed in a position across thebed of a small stream or watercourse 1, the same being supported byposts 2, located upon opposite sides of the Serial No. 176,019. (Nomodel.)

course. The gate is of the hanging type, comprising an uppermostjournal-baton 3, vertical bars 4, and lowermost cross-bar 5. The bar 3is journaled between the supporting-posts 2, the journals beingdesignated 6. The end portion of the bar 3 adjacent one of the journals6 is extended beyond one of the posts 2 and squared, as shown at 7Suitably secured to the squared portion 7 of the journal-bar 3 is asegment 8, which is provided upon the peripheral portion thereof with anotch 9. A detent-bar 10 is slidably mounted adjacent the segment 8,being guided in its movement by a bracket 11, projected from thesupportingposts 2, through which the squared portion 7 of thejournal-bar 3 extends. The upper portion of the detent-bar 1O cooperateswith the segment 8, being adapted to move in and out of the notch 9 uponsaid segment to lock the gate closed when the stream by which the gateis spanned is at a normal height. As before mentioned, the gate isautomatically operable, float means being the actuating medium foraccomplishing the above. The float 12 is located adjacent the detent-bar10, a pivoted arm 18 being secured at its opposite ends to thedetent-bar 10 and the float 12, respectively. The arm 18 is pivoted tothe supporting-posts 2, and a guide-bracket 14, secured to the side ofthe post, prevents lateral play of the pivoted arm 13 ina manner whichwill be seen.

In the operation of the gate the normal position of the same is shown.in Fig. 1, the detent-bar 10 having its upper end resting on the notch9 of the segment 8, thereby looking the gate from movement. Duringfloods it is of course necessary that the gate should be open, since thedebris carried by the stream when in flood condition would seriouslydamage the gate, as will be appreciated However, flooding of the streamactuates the float 12 upwardly, and this movement of the float likewisecauses actuation of the detent-bar 10 to throw the same out ofengagement with the notch-segment 8, thereby permitting a pivotalmovement of the gate outwardly and upwardly which admits of the passageof the obstruction passing down the watercourse.

The gate is extremely simple both as to operation and to structure andfor this reason very desirable.

Having thus described the invention, what is claimed as new is 1. Thecombination with suitable supports, a swinging flood-gate mountedbetween the said supports and having one of its journals extendingbeyond one of the supports, a notched segment mounted upon the aforesaidjournal and actuated thereby, and a float-actuated detcnt-bar forengagement with the notched portion of the segment to lock the gateclosed and permitting automatic opening thereof.

2. The combination with supporting-posts, a flood-gate mounted betweenthe said supporting-posts and having one of its journals extended beyondone of the supporting-posts and squared, a notched segment secured tothe squared portion of the aforesaid journal, a detent-bar mounted uponthe post adjacent the segment for cooperation with the notched portionof the segment, a float disposed adjacent the detent-bar for actuationthereof, and a pivoted arm connected at opposite ends to the float anddetent-bar respectively.

In testimony whereof I afiix my signature in presence of two witnesses.
